.whom Vit, may concern:

e vBe` i't known that'we, `ALBERT H. N ELLER ajIidWaLLIAM LOUDEN, citizens of the -United States, residingat Fairiield, in the county of @'Jelerson andState of Iowa, have invented anew and useful Improvement in Elevated Gamers, of which the following is a specification- `Oui` inventionrelates to that class of elevated carriers adapted to run on an elevated track, and to carry material from one place totanother, and to automatically dump it and f and combination then return to the starting place; and. it consists oi an improvement in the construction of parts set forthlin this s eciication and deiinitely pointed out in the c aims.v Y l 'In the'accompanying drawings forming a part of this specification, Figure 1 is a side perspective of a carrier embodying our invention. Fig. 2 is the Fig. 3 is a transverse 'section on line 3-3of Fig. 2. Fig. 4 is an enlarged horizontal section on line 4-4 of Y. Fig..y 1, ,the ends of the woodwork. being f'broken-away and the ligure being in reversed positionf Fig. 5, isy yan 4enlarged horizontal section on line a5--5 of Fig. 1. Figs. 6, 7, 8 and 9 are enlarged detailed views. Fig. 10 is -a transverse section on line 10-10 of Fig. 8, looking in the direction of the arrow.

eferring to the drawings, A represents a suspended wire or cable track, and W, wheels adapted to run thereon. The wheels are mounted in yokes Y, thelower ends of which are inserted in the upper ends of tubular hangers B, and adapted to swivel therein. The upper ends of the hangers are connected together by means of a bar or pipe C and between their lower ends a receptacle R is supported by means of pivots w ich permit it to turn upside down 'and discharge its load.

The connection of the hangers B with the bar or pipe Cis eilected by means of plates D `which are made to lit their outery surfaces and hold them at substantially right angles with eachother, perforations being made in the plates, hangers and bar, and bolts b being Vused t clamp them together. To hold the plates more securely together their edges are extended beyond hangers and bolts e are used to clamp the outer edges of the plates more rmly vtogether. 'The upper portions of the plates D are'extended above the upper ends of thel i saine showing the 4carrier 1n dumped position.

the outer sides v of the,A

hangers B to receive theyok'eskY. 'Onthe I upper'portions of the lower endsfof the yok'es vannular lips or ribs y' are formed'and recesses are formed on the inner faces of the portions of lthe plates D which [extend above the hangers so as to lit over theannular ribs on the yokes and to permit'them to swivel therein. In this way the hangers carrying the receptacle will be securely heldfby theyokes by means'of the plates while the yokes will be free to swivel in the hangers so as to permit the wheels to run around curves in the track. Itis also preferable to make the lower ends of the y'okes tubular anddo recess the central outer portions of said lower ends so that=the bearings inthe hangerswill be onlyat the upper and lower portion of said inserted ends.

To prevent the wheels `from jumping o" the track wire, the portion ofthe yoke immediately below the wire'is brought across and extended up, and a keeper K is pivoted upon this upwardly extending end. The lower endI of this 4keeper is preferably made heavy so it will overbalance and'hold thesmaller end upright inwhich position it will be in close proximity to the llower'edge of the wheel, so that thewire will be preventedl from getting out. Also, in passing over a switch,-

or where the wire may have a side support, the upper end of the keeperwill be free to turn out of the way and leavea free-opening,

as may be required, and then to immediately and automatically close saidfopening.

The wheels W are mounted on axles a having shouldered ends. The opening in the upper end of the yoke to hold vthe yaxle is made on the inner side ofthe proper size to. admit the body of the axle while on the outer of the shouldered ends Figs. 3 and 9. The central part ofl the -holeis recessed so that the axle will have bearings. only near the edges. The axle may be held in position by a' rivet burla', yor in' any other suitable way. On the outer shouldered end of the axle a washer wis placed` so as to prevent therwheel from comingotf. The axle can be cheaply constructed in this way, and will have the greatest strength and will be securely held-in the yoke. 4 v

The receptacle R is provided `with. two

pivot castings E which aremounted on each Jend near the centers thereof and adapted to rest in perforations in the lower ends .of the hangers B. The hangers are held by the bar as plainly shown in side it is made ofthe proper size to admitone.

l l C.

C and plates D so they will be wider apart than the pivots and their lower ends are set inwardly so they can engage the pivots. The hangers beingtubular, their lower ends are flattened,'as shown by dotted lines in Fig. 6, and then the flattened ends-are bentso as to stand even with one of the tapered sides,y and the main part of the hanger is then bent so as tov stand parallel with this end. In this way the main part of the hanger will be at a little distance from the end of the receptacle so as to allow room for a latching device.

Near the upper edge of one end ofthe receptacle, a plate F is secured, and in it two oppositely set inwardly projecting lingerslf are pivoted so as to. leave an opening between them, and a spring s is used to hold them in operative position. Upon the hanger adjacent to this plate a latch G is pivoted. It is preferably made in two parts and riveted together so as to surround the hanger, tol which it is pivoted by means of a Abolt 71; near its center. Above it a holder H is pivoted to the hanger so as to engage the outer end of the latch. The inner end of the latch is adapted to drop betweenthe fingers f so as to hold the receptacle in loaded position. A latch rod I is pivoted to the inner end ofthe latch at its lower end, and at its upper end to a trip lever J, which in turn is pivoted to an extensiondf/formed on one of the plates D.

An eye is preferably formed on the lower end of the rod and arranged to encircle the central portion of the inner end of the latch where the pieces are riveted together, whiled its upper end is preferably fitted with an open hook i to catch over one end of the trip lever J. This end of the trip lever is preferably made forked with two cross pins g joining the forks together.' The hook of the latch rod catchesover the outer one of these pins and the inner one is used to come in contact 'with a shoulder :d on the extension d, so as to prevent this end of the trip lever from dropping too low. The other end of the trip lever represented by j is set at right angles'to the track wire on which the 'trip block L is mounted. The ends of this trip block are upwardly inclined and the end of the lever j is arranged yto `come in contact with the block L and toibe .pushed downwith it. At the same time the'other end of the leverJ is'raised, which liftsthe rod I and the inner end of the latch G connected t0 it. This raisesl the end of the latch frombetween the fingers f and.

permits the receptacle R to turn on its pivots and dump its load.

Sometimes the receptacle is so nearly on a balance that it will not tip promptly, and in such Cases the latch would be liablel to drop backbetween the fingers f as soon as the end jhad passed lthe stop block, and thus revent the discharge of the load. This lia ility is overcome by theholder H. When the inner G5 end of the latch is lifted by the rod I, its outer l l end will be caught by the holder II and will be held down until released, so that its inner end can not drop between the ingersf. The

outer end of the latch is preferably made with l a diamond shaped head, and the lower end of lthe holder is fitted with a slot so it will drop over and hold down this head. When the receptacle is to be placed in loaded position the latch is easily released, by raising the outer end of the holder so it will free the head and permit the inner end of the latch to drop between the fingers f.

T he track-wire A may be supported in any suitable manner, but at the end where the carrier is unloaded, it is usually set higher than the end in the building where it is loaded. The loaded carrier is gii en a long steady shove which will cause it to run out to the trip block L where the trip mechanism will be operated and the load discharged, as already described. Sometimes it will run past the block L and will be liable to run on to the looped end of the track-wire or on to the tension bolt M, where it may be derailed or otherwise damaged. In order to prevent this, and to insure the safe and positive arrest of the movement of the carrier before it comes in contact wit-h the looped end of the t trackwire, we provide a stop block N which is adapted to catch in the yoke Y and prevent its further movement, and `at' the same time, hold itin such a way that the wheel can not jump the track. This stop is preferably made in two parts rnJ (see Fig. 12) boltedtogether so it may be easily applied to the track wire or removed therefrom. The end next the carrier is made pointed and beveled below the wire so it will pass into and fill the open part of the yoke, while above the wire this end is cut away to permit the wheel to run thereon. It is also provided with a downwardly projecting rib O which will catch avainst the side of the-yoke and prevent it from becoming wedged on the tapering end of the stop. The sides of the stop where it is cut away are widened so as to almost come in Contact with the flanges of the wheel W. In this way should the. stop become twisted to one side of the wire the flange will press down the higher side until they are even and the stop is in the right position to enter the opening of the yoke. By this means no matter how the carrier may be run, nor what the position of the stop` it will always enter the opening of the yoke and safely arrestl the movement ofthe carrier.

The stop is preferably provided with a spring U so that the arrest of the movement l of the carrier will not be too sudden. YVhen a spring is used an openingshould be made in the stop so it will iit loosely andslide readily upon the wire and be responsive to the moyement of the spring. A groove formed in each l of the pieces n of which the stop is preferably com osed as shown in Fiff. 10 so as to admit the track-wire A, will answer the purpose.

In 'this way the stop will be free to slide back and forth along ythe wire to the extent of the spring,` to ease oft' the arrest` ofthe movementof the carrier, and the rebound ofthe spring 4will start the carrier back on its return trip. f Y l l/Vhat we claimis;` 1.
